Disable Bootstrap if you use a plugin for it

Aberration Lite uses the Twitter Bootstrap front-end framework for the structured layout of columns. There are a few other elements that are used, but it’s not the full Bootstrap CSS, so if you use or plan to use a plugin that has Bootstrap 3 or above, you can disable the theme’s own version.

Go to Appearance >> Customize >> Site Options

Look for the “Load Bootstrap” setting and uncheck the box next to it (checked by default to enable it)
